Implemented in #17077, share links are disabled for deactivated users. In my opinion, this should also happen with normal shares to other users. At the moment, a shared folder of a disabled user is still accessable by others.

Describe the solution you'd like
If a user is deactivated, shares from this user should no longer be visible / accesable for others.

Describe alternatives you've considered
I didn't found an easy way of deactivate shares of a user. My (ugly) solution is to backing up oc_share of this user in a table with same schema insert into my_share_backup select * from oc_share where uid_owner='userid'; and setting permissions in oc_share to 0 update oc_share set permissions=0 where uid_owner='userid', restore data on re-activation of user.

Additional context
We need this for 2 reasons:
First, if deactivating someone because auf violation of TOS, noone should be able to change or access the users data.
Second, if accounts expire, they are deactivated but not removed for a grace period. During this time also the data should not be accessable through other accounts.
